Vliv drenážních systémů na odtokové charakteristiky vybraného povodí
ČERMÁKOVÁ, Veronika
This bachelor thesis deals with drainage, especially drainage by drainage systems and their impact on various aspects of nature. The introductory part explains what drainage systems are, what they are used for and what they look like. Furthermore, the history and occurrence of drainage systems in the world and also in the Czech Republic are described. Subsequently, several chapters are devoted to methods of drainage and then a description of drainage systems. The following are the impacts of drainage systems on the water regime of the river basin and on the environment. After processing and analyzing data on runoff and precipitation conditions to a selected catchment area of the Jenínský stream, their behavior during the hydrological years 1984-1985, 2005-2007 and 2011-2013 was compared. In these years, the runoff coefficient was calculated, and subsequently double sum lines were constructed, which show the purpose of identifying changes in the long-term balance of precipitation and runoff.
